Hello,
I am embarking on a project with several high school students to build a multi-use community garden. The kids are very excited about building broken pottery mosaic walls...I want to use cob as the base material. These will be free standing walls encircling an edible water garden and stage, with edible vine plants growing on the back of them.
I have a few concerns in that I am a newbie mostly learning from the internet.
1. Should I be concerned about water damage (considering we have no roof)? How can I prevent water damage?
2. I am hoping to plant things at the base of the walls...should I use a different material for the base?
I appreciate any advice you can give or resources you can point me to
